why ping doesn't work?

I am not experienced with linux but I am in trouble, and I hope to get some good advice here!

I have problem that my networkcard doesn't reach my gateway and local network hosts under linux suse9.1
My networkcard is with static IP, and it seems to me everything with route and IP configuration is OK. ping works fine.
Here is the reply of ifconfig:
linux:/sbin # ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:30:84:6B:C1:C2
inet addr: Bcast: Mask:
inet6 addr: fe80::230:84ff:fe6b:c1c2/64 Scope:Link
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:24 dropped:0 overruns:0 carrier:24
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:2474 (2.4 Kb)
Interrupt:9 Base address:0xb000

lo Link encap:Local Loopback
inet addr: Mask:
inet6 addr: ::1/128 Scope:Host
RX packets:102 errors:0 dropped:0 overruns:0 frame:0
TX packets:102 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:7528 (7.3 Kb) TX bytes:7528 (7.3 Kb)

sit0 Link encap:IPv6-in-IPv4
NOARP MTU:1480 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)

The only thing that seems strange to me is the line:

TX packets:0 errors:24 dropped:0 overruns:0 carrier:24

Could it be a IRQ problem and if so, how can I fix it?
In the boot message there are also some other devices using IRQ 9 ... and, the most confusing for me my data /proc/interrupts is empty. There is nothing in there... (the same with ioports).

Do you have any suggestions, what can I try?

Hi, the ping always work.
There's not an IRQ problem because you chan see you network card in the list with an assigned ip.

Try to ping

Try to ping your router (with IP and not DNS name)

Try from another machine to ping your box

Check your routing table (with command route)

Check your resolv.conf file and watch if your DNS are OK.

Hope this helps.
Bye Kess
